Question is title.

In the past I've installed many distros on many older PCs, but never used linux properly (although slowly moving over to avoid win11). I've also had a heap of history with windows installs.

A family member has been testing Mint on an old laptop and is going well. This is a trial run before I update their iMac laptop (not sure what one but no longer supposed by OS updates).

I've never booted to an iMac BIOS or installed over top of apple.

• Is this going to be like installing over windows?
• What issues can I expect?
• Should I consider another distro?
